having to install a barrel on an ar. tight on cash. any suggestions on a cheap go and no go gauge.

For an AR stuff it on there tighten ring and go for it. I haven't used one in years for an AR.

Rent them, cheaper than buying for a one time use.

If the barrel extension is already installed you don't need a headspace gauge. Unless you are doing the threading and chambering the barrel should come with an extension that has already been set for headspace.

I used masking tape on case heads. 3 layers should not chamber. 2 layers should have a little resistance.

This is actually a good common sense and cheap alternative to buying or renting a set of gauges. I've used this method four times already and it most definitely worked. I first learned about it on the Savage Barrel-Nut forums.

If you plan on using a specific brand or head stamp of brass, this method works particularly will. There's a well respected nationally known gunsmith named Gordy Gritters that uses this method. He has a video on youtube showing how it's done.

few types of brass, mostly fc brass for plinking cut and neck for 300blk, and per necked lc brass for hunting loads.

Note post #4 is the correct answer folks.

I have checked a couple hundred AR bolts. I have yet to find more than a .001" variation.

went on and ordered a go gage, looked up some stuff about using them on youtube. had a video where a gunsmith (can't remember his name) added a piece of scotch tape to the back of the go gage and subbed it in for a no gage.

may not be a one time use. have a friend who is thinking of building a 300bo.
well try some of the other methods that was post in these thread as well. thank you for the replies.

As mentioned post 4 is the correct one.

with what happen to me recently, I want to be over cautions then not be. if that makes any since.

I am rebuilding for an bad mistake and want to make sure everything is right. I have reorganized my reloading room. finding ways to keep from getting distracted and knowing what is in what.
